Abstract: The integration of solid oxide fuel cells (SOFe) in power generation plants leads to novel process engineering aspects. In comparison with conventional electricity production techniques fuel cell power plants attain higher efficiencies and lower emissions. The present study deals with the energetical and economical optimization of a compact SOFC power plant with 200 kW power output as a sensitivity analysis. Parameters with respect to efficiency and cost will be determined for the main power plant components. The objective of this study is to analyze and optimize power plant concepts with respect to present technical limitations. For this different configurations of power plant components will be regarded: anode and cathode gas recycling, steam generation, natural gas reforming, heat removal and the arrangement of heat exchangers for heat recovery. Particularly the correlation between the electrochemical cell parameters and the process engineering expenditure will be investigated. The influence of the power plant operation conditions pre-reforming, fuel utilization, cell voltage, operating temperature and temperature rise across the SOFC stack will be shown. With an evaluation of economic efficiency for possible power plant modes of operation the cost of electricity production will be calculated in dependence on various operating parameters.
